I noticed too late there is polyacrylate in this product. That's plastic! I switched to another brand because i don't think eating plastic is good for anyone.
Otherwise NAC is a great supplement: removes toxins from your body by helping liver to work as it should. Great hangover medicine as well :)

<font color="red"><strong>August 2012 - Note form Jarrow Formulas:</strong></font> The polyacrylate polymer is GRAS. The material is widely used in dietary supplements although can be represented in multiple ways on a label including the trademark Carbopol, carbomer homopolymer and carboxypolymethylene. Finally, the research indicates that due to its size, the polyacrylate polymer employed in this product is not absorbed through the intestines and therefore poses no safety concern. There is a very good reason for NAC Sustain: The half-life of NAC is relatively brief. Carbopol is a biomucoadhesasnt. It keeps the tablet at the site of maximum absorption, at or near the upper small intestines. The tablet slowly erodes, thus there is a continuous release for a couple of hours instead of the whole thing being essentially gone in one hour. The tablet can take up to two hours to release the contents plus the hour of half-lives, thus the dose lasts three hours or more. This gives a real boost to the production of GSH (glutathione) and the Phase I detoxification pathway of the liver. If one chooses to not utilize the benefits of Carbopol then the standard <a href="http://www.iherb.com/Jarrow-Formulas-N-Acetyl-L-Cysteine-500-mg-200-Capsules/235" target="_blank">Jarrow Formulas NAC capsule</a> is also an option. <br />
